Solve (9x-4)^2=18 using the square root method

Damm [24]

Answer:

x = 4/9 + sqrt(2)/3 or x = 4/9 - sqrt(2)/3

Step-by-step explanation:

Solve for x over the real numbers:

(9 x - 4)^2 = 18

Take the square root of both sides:

9 x - 4 = 3 sqrt(2) or 9 x - 4 = -3 sqrt(2)

Add 4 to both sides:

9 x = 4 + 3 sqrt(2) or 9 x - 4 = -3 sqrt(2)

Divide both sides by 9:

x = 4/9 + sqrt(2)/3 or 9 x - 4 = -3 sqrt(2)

Add 4 to both sides:

x = 4/9 + sqrt(2)/3 or 9 x = 4 - 3 sqrt(2)

Divide both sides by 9:

Answer: x = 4/9 + sqrt(2)/3 or x = 4/9 - sqrt(2)/3

Please helpppppp mee thanks everyone

Answer:

$\frac{32}{35}$

Step-by-step explanation:

To answer this question you need to get the same denominator (bottom number of a fraction ) on both values

Because 7 is a factor of 35, you can multiply the whole fraction by 5, (so that the first fraction has a denominator of 35 which is the same as the other value)

$\frac{4}{7}$ ×5 $= \frac{20}{35}$

then you add them up but remember if the denominator is the same you do <u>not </u> add them.

$\frac{20}{35} +\frac{12}{35} = \frac{32}{35}$

Hope the answer is right, Ask if unsure :)

If Q is directly proportional to P and Q = 28 when P = 4

nasty-shy [4]

I) Q = 7*P
ii) Q = 35
iiI) 42 = 7*P
42 / 7 = P
so P = 6
